No separate discount code for military, veteran, or LE/first-responder buyers — site pricing is already set to be competitive for these groups. Discounts run through two channels only: the Rewards Program (sign up via the Rewards button on the site) and the mailing list.

HK Parts does not offer coupons or promo codes for any occasion (Cyber Monday, first-time buyers, seasonal sales, etc.). Any codes found online aren't affiliated with HK Parts and won't work at checkout. Pricing discounts come only through the Rewards Program and mailing list.

Yes, case-by-case, in two situations: a sale price on your own purchase within 7 days after buying, honored retroactively; or a competitor's current, in-stock listing at a lower price (excludes items below MAP or our minimum margin). Email support@hkparts.net or (801) 987-3494, Mon–Fri, 8:00am–3:00pm MST with the item, order number, and a link or reference to the lower price.

Submit a preliminary order listing the specific part numbers and quantities you need, and it'll be reviewed for a possible price adjustment. This is evaluated case-by-case rather than through a published discount tier.

Sales tax is only charged on orders shipping to a Utah address — everywhere else, no tax applies. If you're in Utah and qualify for tax-exempt status (veteran, disabled veteran, government agency), create an account and submit your tax exemption documentation; your account is updated so future orders reflect it.
